The Dyson Airblade is impressive

If you live in the UK (I’m not sure how far these little beasties have travelled) then you’ve almost certainly encountered one of Dyson’s Airblades in a toilet or rest room near you. In the past, not that many years ago, hand dryers were weak and wimpy affairs, which seemed designed to do little more than push the water up your arms so that the sleeves of your shirt or jersey would absorb the moisture. No real drying went on. Then came Dyson, with his big engine and novel “no rubbing” design.
